Why does your Aechmea fendleri have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
Mealybugs are common pests for Aechmea species that secrete a white, waxy, cottony substance to protect themselves. They feed on the plant's sap, often congregating in the leaf axils or near the base of the rosette.
Certain types of scale insects produce a white, flocculent coating that can resemble cotton. These pests attach to the leaves or stem of the Bromeliad and suck nutrients, causing localized discoloration.
High humidity in the central tank of the Aechmea can trigger fungal pathogens like Botrytis. In its early stages, it may appear as light-colored, fuzzy patches on decaying organic matter within the leaf bases.
